What are the implications of intermittent nature of solar power?

However, the implications of intermittent nature need to be examined. Intermittency of solar PV power affects the balance between supply and demand. When supply-demand balance is not maintained, power system frequency deviates from steady state values; consequently, system stability and reliability are jeopardized (Kundur, Paserba et al. 2004).
